Abstract
In this study the effects of a closed-loop recycling methodology are evaluated for degradation using thermoplastic ocmposites based on discontinuous fibres. The process comprises two fundamental steps: reclamation and remanufacture. The material properties are analysed over two recycling loops. Carbon fibre reinforced polypropylene (CFPP) specimens show no decrease in mechanical properties over repeated recycling loops, the final specimens show an increase of 26 % and 43 % in ultimate tensile strength and ultimate strain, respectively. These are attributed to cumulative matrix residue on the fibre surface after reclamation and subsequently increased fibre-matrix adhesion. The improvement of CFPP properties validate the potential of this proof-of-concept, closed-loop recyclable material. Future studies will investigate alternative, higher performance matrices.
